According to an embodiment, the display device 160 may include touch circuitry adapted to detect a touch, or sensor circuitry (e.g., a pressure sensor) adapted to measure the intensity of force incurred by the touch.

The audio module 170 may convert a sound into an electrical signal and vice versa. According to an embodiment, the audio module 170 may obtain the sound via the input device 150, or output the sound via the sound output device 155 or a headphone of an external electronic device (e.g., an electronic device 102) directly (e.g., wiredly) or wirelessly coupled with the electronic device 101.

The sensor module 176 may detect an operational state (e.g., power or temperature) of the electronic device 101 or an environmental state (e.g., a state of a user) external to the electronic device 101, and then generate an electrical signal or data value corresponding to the detected state. According to an embodiment, the sensor module 176 may include, for example, a gesture sensor, a gyro sensor, an atmospheric pressure sensor, a magnetic sensor, an acceleration sensor, a grip sensor, a proximity sensor, a color sensor, an infrared (IR) sensor, a biometric sensor, a temperature sensor, a humidity sensor, or an illuminance sensor.

The battery 189 may supply power to at least one component of the electronic device 101. According to an embodiment, the battery 189 may include, for example, a primary cell which is not rechargeable, a secondary cell which is rechargeable, or a fuel cell.

The communication module 190 may support establishing a direct (e.g., wired) communication channel or a wireless communication channel between the electronic device 101 and the external electronic device (e.g., the electronic device 102, the electronic device 104, or the server 108) and performing communication via the established communication channel. The communication module 190 may include one or more communication processors that are operable independently from the processor 120 (e.g., the application processor (AP)) and supports a direct (e.g., wired) communication or a wireless communication. According to an embodiment, the communication module 190 may include a wireless communication module 192 (e.g., a cellular communication module, a short-range wireless communication module, or a global navigation satellite system (GNSS) communication module) or a wired communication module 194 (e.g., a local area network (LAN) communication module or a power line communication (PLC) module). A corresponding one of these communication modules may communicate with the external electronic device via the first network 198 (e.g., a short-range communication network, such as Bluetooth™, wireless-fidelity (Wi-Fi) direct, or infrared data association (IrDA)) or the second network 199 (e.g., a long-range communication network, such as a cellular network, the Internet, or a computer network (e.g., LAN or wide area network (WAN)). These various types of communication modules may be implemented as a single component (e.g., a single chip), or may be implemented as multi components (e.g., multi chips) separate from each other. The wireless communication module 192 may identify and authenticate the electronic device 101 in a communication network, such as the first network 198 or the second network 199, using subscriber information (e.g., international mobile subscriber identity (IMSI)) stored in the subscriber identification module 196.

According to an embodiment, the antenna module 197 may include an antenna including a radiating element composed of a conductive material or a conductive pattern formed in or on a substrate (e.g., PCB). According to an embodiment, the antenna module 197 may include a plurality of antennas. In such a case, at least one antenna appropriate for a communication scheme used in the communication network, such as the first network 198 or the second network 199, may be selected, for example, by the communication module 190 (e.g., the wireless communication module 192) from the plurality of antennas. The signal or the power may then be transmitted or received between the communication module 190 and the external electronic device via the selected at least one antenna. According to an embodiment, another component (e.g., a radio frequency integrated circuit (RFIC)) other than the radiating element may be additionally formed as part of the antenna module 197.

At least some of the above-described components may be coupled mutually and communicate signals (e.g., commands or data) therebetween via an inter-peripheral communication scheme (e.g., a bus, general purpose input and output (GPIO), serial peripheral interface (SPI), or mobile industry processor interface (MIPI)).

According to an embodiment, commands or data may be transmitted or received between the electronic device 101 and the external electronic device 104 via the server 108 coupled with the second network 199. Each of the electronic devices 102 and 104 may be a device of a same type as, or a different type, from the electronic device 101. According to an embodiment, all or some of operations to be executed at the electronic device 101 may be executed at one or more of the external electronic devices 102, 104, or 108. For example, if the electronic device 101 should perform a function or a service automatically, or in response to a request from a user or another device, the electronic device 101, instead of, or in addition to, executing the function or the service, may request the one or more external electronic devices to perform at least part of the function or the service. The one or more external electronic devices receiving the request may perform the at least part of the function or the service requested, or an additional function or an additional service related to the request, and transfer an outcome of the performing to the electronic device 101. The electronic device 101 may provide the outcome, with or without further processing of the outcome, as at least part of a reply to the request. To that end, a cloud computing, distributed computing, or client-server computing technology may be used, for example.

FIG. 2 is a block diagram 200 illustrating the camera module 180 according to various embodiments. Referring to FIG. 2, the camera module 180 may include a lens assembly 210, a flash 220, an image sensor 230, an image stabilizer 240, memory 250 (e.g., buffer memory), or an image signal processor 260. The lens assembly 210 may collect light emitted or reflected from an object whose image is to be taken. The lens assembly 210 may include one or more lenses. According to an embodiment, the camera module 180 may include a plurality of lens assemblies 210. In such a case, the camera module 180 may form, for example, a dual camera, a 360-degree camera, or a spherical camera. Some of the plurality of lens assemblies 210 may have the same lens attribute (e.g., view angle, focal length, auto-focusing, f number, or optical zoom), or at least one lens assembly may have one or more lens attributes different from those of another lens assembly. The lens assembly 210 may include, for example, a wide-angle lens or a telephoto lens.

The flash 220 may emit light that is used to reinforce light reflected from an object. According to an embodiment, the flash 220 may include one or more light emitting diodes (LEDs) (e.g., a red-green-blue (RGB) LED, a white LED, an infrared (IR) LED, or an ultraviolet (UV) LED) or a xenon lamp. The image sensor 230 may obtain an image corresponding to an object by converting light emitted or reflected from the object and transmitted via the lens assembly 210 into an electrical signal. According to an embodiment, the image sensor 230 may include one selected from image sensors having different attributes, such as a RGB sensor, a black-and-white (BW) sensor, an IR sensor, or a UV sensor, a plurality of image sensors having the same attribute, or a plurality of image sensors having different attributes. Each image sensor included in the image sensor 230 may be implemented using, for example, a charged coupled device (CCD) sensor or a complementary metal oxide semiconductor (CMOS) sensor.

The image stabilizer 240 may move the image sensor 230 or at least one lens included in the lens assembly 210 in a particular direction, or control an operational attribute (e.g., adjust the read-out timing) of the image sensor 230 in response to the movement of the camera module 180 or the electronic device 101 including the camera module 180. This allows compensating for at least part of a negative effect (e.g., image blurring) by the movement on an image being captured. According to an embodiment, the image stabilizer 240 may sense such a movement by the camera module 180 or the electronic device 101 using a gyro sensor (not shown) or an acceleration sensor (not shown) disposed inside or outside the camera module 180. According to an embodiment, the image stabilizer 240 may be implemented, for example, as an optical image stabilizer.

The memory 250 may store, at least temporarily, at least part of an image obtained via the image sensor 230 for a subsequent image processing task. For example, if image capturing is delayed due to shutter lag or multiple images are quickly captured, a raw image obtained (e.g., a Bayer-patterned image, a high-resolution image) may be stored in the memory 250, and its corresponding copy image (e.g., a low-resolution image) may be previewed via the display device 160. Thereafter, if a specified condition is met (e.g., by a user's input or system command), at least part of the raw image stored in the memory 250 may be obtained and processed, for example, by the image signal processor 260. According to an embodiment, the memory 250 may be configured as at least part of the memory 130 or as a separate memory that is operated independently from the memory 130.

The image signal processor 260 may perform one or more image processing with respect to an image obtained via the image sensor 230 or an image stored in the memory 250. The one or more image processing may include, for example, depth map generation, three-dimensional (3D) modeling, panorama generation, feature point extraction, image synthesizing, or image compensation (e.g., noise reduction, resolution adjustment, brightness adjustment, blurring, sharpening, or softening). Additionally or alternatively, the image signal processor 260 may perform control (e.g., exposure time control or read-out timing control) with respect to at least one (e.g., the image sensor 230) of the components included in the camera module 180. An image processed by the image signal processor 260 may be stored back in the memory 250 for further processing, or may be provided to an external component (e.g., the memory 130, the display device 160, the electronic device 102, the electronic device 104, or the server 108) outside the camera module 180. According to an embodiment, the image signal processor 260 may be configured as at least part of the processor 120, or as a separate processor that is operated independently from the processor 120. If the image signal processor 260 is configured as a separate processor from the processor 120, at least one image processed by the image signal processor 260 may be displayed, by the processor 120, via the display device 160 as it is or after being further processed.

According to an embodiment, the electronic device 101 may include a plurality of camera modules 180 having different attributes or functions. In such a case, at least one of the plurality of camera modules 180 may form, for example, a wide-angle camera and at least another of the plurality of camera modules 180 may form a telephoto camera. Similarly, at least one of the plurality of camera modules 180 may form, for example, a front camera and at least another of the plurality of camera modules 180 may form a rear camera.

Herein is disclosed an electronic device and a method for securing personal information included in an image. An aspect of an embodiment disclosed herein is to prevent the unintended leakage of the user's personal information that may be included in the image.

According to certain embodiments, an electronic device and a method for securing personal information included in an image can prevent personal information included in the image from being leaked to the public.

According to certain embodiments, in an electronic device and a method for securing personal information included in an image, the user's personal information included in the image may be displayed only on the user's electronic device.

FIG. 3 is a block diagram illustrating operations of an electronic device and an external electronic device according to an embodiment.

In an embodiment, the electronic device 101 may include an image sensor 321, an image signal processor (ISP) 323, and a memory 325. An external electronic device 300 (e.g. the electronic device 104 or the server 108) may include a recognition module 331, an ISP 333, and a storage 335. The recognition module 331 may be a logical module and may be implemented using a processor of the external electronic device 300 together with software. The ISP 333 may also be implemented using the processor of the external electronic device 300. In that example, the processor of the external electronic device 300 may perform both recognition and image processing. Although not illustrated, the electronic device 101 may include a communication module (e.g. the communication module 190 in FIG. 1) which can transmit or receive data to or from the external electronic device 300. The external electronic device 300 may include a communication module which can transmit or receive data to or from the electronic device 101. According to an embodiment, the electronic device 101 may include a recognition module 327. The recognition module 327 disposed in the electronic device 101 may be configured to perform functions identical to some of functions of the recognition module 331. For example, the recognition module 327 may be hardware or software configured to recognize a face in an image, and may be able to more simply and quickly recognize the face than the external electronic device 300 (e.g. the server) because the recognition is done locally rather than requiring the image to be transmitted over a network.

In an embodiment, the image sensor 321 (e.g. the image sensor 230 in FIG. 2) may acquire an image of an external object, and may generate a raw image 322 corresponding thereto. The raw image 322 may be implemented in various formats, such as Bayer format, color filter array (CFA) pattern, layer structure generated by sensing three colors for each pixel, format generated by different parallax acquired by each pixel, and the like. The image sensor 321 may transfer the raw image 322 to the ISP 323 (e.g. the image signal processor 260 in FIG. 2) and/or the recognition module 327.

In an embodiment, the image sensor 321 may generate a small raw image 326. The image sensor 321 may generate the small raw image 326 by reducing the raw image 322 by, for example, reducing its resolution. For example, the image sensor 321 may generate the small raw image 326 from the raw image 322 by using various down-scaling methods or down-sampling methods. The data volume of the small raw image 326 may be smaller than that of the raw image 322 due to the image sensor 321 adjusting the resolution of the raw image 322, filtering the raw image 322 through one or more frequency bands, and/or selecting one or more bit-plane levels of the raw image 322. For example, the image sensor 321 may generate the small raw image 326 by extracting a low-frequency band from the raw image 322. In another example, the image sensor 321 may generate the small raw image 326 by selecting some from among a multiple bit-plane levels of the raw image 322. The image sensor 321 may transmit the small raw image 326 to the external electronic device 300 through the communication module. The small raw image 326 may include at least a part of the raw image 322, and may be a smaller data file than the raw image 322. If the small raw image 326, instead of the raw image 322, is transmitted to the external electronic device, volume of data transmission is reduced, and thus the image can be more quickly transmitted to the external electronic device 300. In another embodiment, a processor (e.g. the processor 120) of the electronic device 101, instead of the image sensor 321, may generate the small raw image 326, and may transmit the generated small raw image 326 to the external electronic device 300 through the communication module. The processor 120 may include a microprocessor or any suitable type of processing circuitry, such as one or more general-purpose processors (e.g., ARM-based processors), a Digital Signal Processor (DSP), a Programmable Logic Device (PLD), an Application-Specific Integrated Circuit (ASIC), a Field-Programmable Gate Array (FPGA), a Graphical Processing Unit (GPU), a video card controller, etc. In addition, it would be recognized that when a general purpose computer accesses code for implementing the processing shown herein, the execution of the code transforms the general purpose computer into a special purpose computer for executing the processing shown herein. Certain of the functions and steps provided in the Figures may be implemented in hardware, software or a combination of both and may be performed in whole or in part within the programmed instructions of a computer. No claim element herein is to be construed under the provisions of 35 U.S.C. § 112(f), unless the element is expressly recited using the phrase “means for.” In addition, an artisan understands and appreciates that a “processor” or “microprocessor” may be hardware in the claimed disclosure. Under the broadest reasonable interpretation, the appended claims are statutory subject matter in compliance with 35 U.S.C. § 101.

In an embodiment, the image sensor 321 may transmit a compressed raw image 322 to the ISP 323, the external electronic device 300, or the recognition module 327. The image sensor 321 may compress the raw image 322 and may store the compressed raw image 322 in an internal memory of the image sensor 321.

In an embodiment, the recognition module 331 of the external electronic device 300 may acquire the small raw image 326 through the communication module, and may segment the small raw image 326 into at least one image segment. The recognition module 331 may recognize the at least one image segment that resulted from the segmentation. For example, the recognition module 331 may segment the small raw image 326, and may identify at least one image segment from the small raw image 326 that resulted from the segmentation. The recognition module 331 may recognize the image segment by applying an object recognition algorithm or a text recognition algorithm to the image segment. Thus, the recognition module 331 of the external electronic device 300 may recognize at least one image segment by using various recognition algorithms, such as a machine learning or deep learning algorithm. For example, the recognition module 331 of the external electronic device 300 may acquire information associated with an image segment in which pixel coordinates (100, 101), (100, 102), (102, 102), and (102, 103) represent “person's teeth.” The pixel coordinates may correspond to pixel coordinates of the raw image 322. The recognition module 331 may acquire, for example, classification information indicating that the small raw image 326 is classified as a category in which “a person is on a street.” The recognition module 331 may acquire classification information by using the recognition result, or may acquire classification information by color distribution, etc. in the small raw image 326 without employing recognition. The recognition module 331 may generate correction segment information 332 including at least one of the classification information or the information associated with the at least one image segment acquired through the above-described process. The recognition module 331 may transmit the correction segment information 332 to the electronic device 101. The ISP 323 may correct the raw image 322 by using the correction segment information 332, and thus may generate a corrected image 324. The corrected image 324 may have, for example, a YUV format. The corrected image 324 may be stored in the memory 325. Alternatively, the corrected image 324 may be compressed by, for example, JPEG method, and the compressed image may be stored in the memory 325. According to an embodiment, the correction segment information may be generated by the recognition module 327 of the electronic device 101 and may then be transferred to the ISP 323.

In an embodiment, the raw image 322 provided from the image sensor 321 may be transmitted to the external electronic device 300, regardless of whether the small raw image 326 is transmitted. The external electronic device 300 may generate another correction segment information by using the raw image 322. By using the raw image 322, which is larger than the small raw image 326, the external electronic device 300 (e.g. the ISP 333 of the external electronic device 300) may generate correction segment information based on the raw image 322 in addition to the correction segment information generated from the small raw image 326, and may designate the same as extended correction segment information. Since the raw image 322 may include more information than the small raw image 326, the external electronic device 300 may generate more detailed correction segment information from the raw image 322. In one embodiment, the external electronic device 300 (the ISP 333 of the external electronic device 300) may only generate extended correction segment information from the raw image 322. Alternatively, the external electronic device 300 (e.g. the ISP 333 of the external electronic device 300) may generate extended correction segment information by using the raw image 322 as well as correction segment information generated from the small raw image 326.

In an embodiment, since the raw image 322 is larger than the small raw image 326, the small raw image 326 may be first transmitted to the external electronic device 300, followed by transmission of the raw image 322 to the external electronic device 300. For example, the raw image 322 may be transmitted to the external electronic device 300 while the ISP 323 corrects the raw image 322 using correction segment information generated from the small raw image 326. The raw image 322 may be uploaded to the external electronic device 300 as generated by the image sensor 321. Alternatively, a pre-processed version of the raw image 322, which has undergone lens distortion correction and noise removal, may be uploaded. The pre-processing may be performed by the external electronic device 300. The external electronic device 300 may perform demosaic processing or image format modification, or other pre-processing to improve the image recognition done by the recognition module 331. The ISP 333 of the external electronic device 300 may correct the received raw image 322. The external electronic device 300 may correct the raw image 322 by using the correction segment information 332 and/or the extended correction segment information. As the raw image 322 may be of higher quality than the small raw image 326, the ISP 333 of the external device 300 may acquire more detailed segment information from the higher quality image. The ISP 333 may generate the extended correction segment information by using the generated correction segment information and the raw image 322 together. The ISP 333 may generate a high quality image 334 by correcting the raw image 322 by using the extended correction segment information. The high quality image 334 may be stored in the storage 335 of the external electronic device 300 and may be downloaded to the electronic device 101.

FIG. 4 is a block diagram of electronic devices according to an embodiment.

A first electronic device 470 (e.g. the electronic device 102 or the server 108) according to an embodiment may be implemented as a cloud server. The first electronic device 470 may perform network management, cloud service management relating to services and rights to be provided, and storage management, with respect to servers constituting a cloud system and with respect to electronic devices (e.g. a second electronic device 400) connectable to the cloud system.

The first electronic device 470 according to an embodiment may include a processor 471, a database 478, a raw image storage 479, and an image storage 480. The processor 471 according to an embodiment may include a pre-processing module 474, an image recognition module 473, an ISP 476, an encoder 475, a monitoring module 472, a test target acquisition module 481, an image comparison module 482, and a correction target determination module 483. According to an embodiment, the ISP 476 may be implemented as separate hardware.

According to an embodiment, the pre-processing module 474, the image recognition module 473, the encoder 475, the monitoring module 472, the test target acquisition module 481, the image comparison module 482, and the correction target determination module 483 may be logical modules. Thus, operations performed thereby may be performed by the processor 471 or a processor (e.g. a first processor 430 or a second processor 412) of the second electronic device 400.

According to an embodiment, at least one of the pre-processing module 474, the image recognition module 473, the ISP 476, the encoder 475, the monitoring module 472, the test target acquisition module 481, the image comparison module 482, or the correction target determination module 483 may be implemented as a separate hardware module in the processor 471 of the first electronic device 470 or a separate hardware module in the processor (e.g. the first processor 430 or the second processor 412) of the second electronic device 400.

The pre-processing module 474 according to an embodiment may pre-process an image (e.g. raw image or small raw image) received from the second electronic device 400 and may transmit the pre-processed image to the image recognition module 473, the raw image storage 479, or the ISP 476. According to an embodiment, the pre-processing may include decoding the image file received from the second electronic device 400 to generate a raw image.

The image recognition module 473 (e.g. the recognition module 331 in FIG. 3) according to an embodiment may receive an image (e.g. raw image or small raw image) from the second electronic device 400 through a communication module of the first electronic device 470 or via pre-processing module 474 thereof.

The image recognition module 473 according to an embodiment may recognize the received image by using various algorithms, such as (1) an object recognition algorithm, 2) a text recognition algorithm, or 3) a recognition algorithm acquired by applying machine learning or deep learning to an image storage (e.g. the raw image storage 479 and/or the image storage 480)). The image recognition module 473 may store the recognized result in a database (e.g. the raw image storage 479) in association with to the received image and/or may transmit the recognized result to the second electronic device 400. For example, the image recognition module 473 may recognize at least one object (e.g. a person, the sky, a cloud, a cat, a puppy, etc.) in the received image. The object may be recognized in an image segment within the image. According to an embodiment, the image recognition module 473 may recognize an object in an image corresponding to user information. For example, the user information may be acquired from an image (e.g. a picture of family or acquaintance, or a house picture) stored in the database 478. The recognized result may include position information (e.g. pixel coordinates) of an image segment and identification information of an object in the image segment. Further the recognized result may be used when the ISP 476 processes an image and when the test target acquisition module 481 selects a test target.

The image recognition module 473 according to an embodiment may store identification information of an object (or objects) recognized in the received image as category information of the received image, which may be stored in a database (e.g. the raw image storage 479) in associated with the category information. For example, the image recognition module 473 may store the identification information as tag information of a received image and store the same in a database. Alternatively, the image recognition module 473 may transmit the identification information to the second electronic device 400. The category information may include multiple categories which are hierarchically classified. For example, if a “cat” is recognized as an object in an image segment, the image recognition module 473 may configure identification information indicating an “animal” as a superordinate category of the corresponding image and may configure identification information indicating the “cat” as a subordinate category of the corresponding image. According to an embodiment, the first electronic device 470 may receive category information corresponding to an image (e.g. raw image or small raw image) from the second electronic device 400, and may store the category information in the database in relation to the corresponding image.

The ISP 476 according to an embodiment may perform image processing (e.g. correction) on the received image by adjusting various values (e.g. brightness, shade, color, saturation, color temperature, sharpness, color harmony, vividness, contrast, or hue saturation value (HSV)) of the received image. The image processing may be performed based on recipe information (e.g. image segment, layer, vector, scene category, etc.) acquired through image recognition. For example, the ISP 476 may recognize an image segment, in which an object is positioned, of an image as a correction target, and may correct the image segment. The ISP 476 may receive additional information (e.g. feature vector indicating a feature of an object or a part thereof (e.g. a hair)) corresponding to the recipe information from the database 478, and may use the additional information for image processing. The processed image may be transmitted to the second electronic device 400 or the encoder 475, or may be stored in a database (e.g. the image storage 480). The image processing may include functions, such as white balance, color adjustment, noise reduction, sharpness effect, and detail enhancement. The functions may be performed for each image segment on the basis of the recipe information.

The encoder 475 according to an embodiment may generate an image file (e.g. JPEG, MPEG, 360-degree panorama, etc.) by encoding the corrected image processed by the ISP 476 or a raw image stored in the raw image storage 479. The image file generated by the encoder 475 may be transmitted to the second electronic device 400 through the communication module of the first electronic device 470, or may be stored in the database (e.g. the image storage 480).

The monitoring module 472 according to an embodiment may determine that the ISP 476, which is configured to process images in the first electronic device 470, has been changed from a first ISP 476 a to a second ISP 476 b. For example, the second ISP 476 b may perform an upgraded correction method from that of the first ISP 476 a.

In response to the determination made by the monitoring module 472, the test target acquisition module 481 according to an embodiment may acquire some of the images stored in the database (e.g. the raw image storage 479 or the image storage 480) as test targets for image processing. According to one embodiment, if the test targets are acquired from the raw image storage 479, image processing may be performed by the correction method of the first ISP 476 a, to which a modification (e.g. replacement or upgrade) is not applied, and also the correction method of the second ISP 476 b, to which modification has been applied. According to one embodiment, if the test targets are acquired from the image storage 480, image processing may be performed by on the second ISP 476 b.

The test target acquisition module 481 according to an embodiment may acquire an equal number of test targets for one or more categories. For example, the test target acquisition module 481 may acquire the same number of images classified to the “puppy” category as the number of images classified as the “cat” category.

In an embodiment, each of the first ISP 476 a and the second ISP 476 b may correct the test targets acquired by the test target acquisition module 481, i.e. by adjusting various values (e.g. brightness, shade, color, saturation, color temperature, sharpness, color harmony, vividness, contrast, or HSV) of each the test targets. According to an embodiment, if a test target is a compressed image acquired from the image storage 480, the image may be decompressed first and then corrected.

The image comparison module 482 according to an embodiment may calculate, for each of the test targets acquired from the databases (e.g. the raw image storage 479), the difference between the values obtained through image correction by the first ISP 476 a and obtained through image correction by the second ISP 476 b. For example, the image comparison module 482 may select, as a comparison target, at least one from among brightness, shade, color, saturation, color temperature, sharpness, color harmony, vividness, contrast, or HSV on the basis of a tuning policy (e.g., effect) that is expected as the correction method is changed. For example, if the effect expected by the change of the correction method is an increase in contrast, the image comparison module 482 may calculate, for each of the test targets, the difference between the contrast values obtained by the image correction of the first ISP 476 a and the image correction of the second ISP 476 b. If the expected effect is an increase in the vividness of an image segment where the HSV has about 30 to 60 degrees, the image comparison module 482 may calculate, for each of the test targets, the difference between the color values obtained by image correction of the first ISP 476 a and the image correction of the second ISP 476 b.

The image comparison module 482 according to an embodiment may calculate, for each of the test targets acquired from the database (e.g. the image storage 480), the difference between a value of the images before and after the correction by the second ISP 476 b.

The image comparison module 482 according to an embodiment may classify the test targets into two groups on the basis of the comparison result. For example, the image comparison module 482 may classify the test targets into a superordinate group having a difference in value exceeding a predetermined threshold and a subordinate group having a difference in value below the threshold. Here, the difference in value may refer to 1) the difference between values in images obtained by image correction of the first ISP 476 a and image correction of the second ISP 476 b, or 2) the difference between values in images before and after correction by the second ISP 476 b.

The correction target determination module 483 according to an embodiment may determine a correction target on the basis of the comparison result acquired by the image comparison module 482. Here, the correction target may be selected from among images stored in the databases (e.g. the raw image storage 479 or the image storage 480). The correction target may undergo image processing by a correction method (e.g., the second ISP 476 b) to which a modification (e.g. replacement or upgrade) has been applied, and then may be stored in the database (e.g. the image storage 480) and/or may be transmitted to the second electronic device 400. According to one embodiment, the correction target determination module 483 may recognize the subordinate group as a group having the correction effect which is not as expected, and accordingly, may identify a category of images belonging to the subordinate group, and may determine that images corresponding to the category of the subordinate group are not subject to be corrected. The correction target determination module 483 may select at least one test target from the superordinate group and may determine images corresponding to the category of the selected test target as correction targets among the images stored in the databases (e.g. the raw image storage 479 or the image storage 480).

According to an embodiment, category information used to determine the correction target may include information acquired by the image recognition module 473 and then stored in the database (e.g. the raw image storage 479 or the image storage 480) in association with the corresponding image. Further, the category information may include information which is received from an external device (e.g. the second electronic device 400) and stored in the database as metadata of the corresponding image together with the corresponding image.

In an embodiment, according to the comparison result acquired by the image comparison module 482, a category may be commonly associated with the test targets of the superordinate group or test targets of the subordinate group. For example, a first test target having a “cat” may belong to the superordinate group, while a second test target also having a “cat” may belong to the subordinate group. Thus, images that fall into both superordinate and subordinate groups may have less correction effects than expected. Therefore, the correction target determination module 483 may exclude images having a “cat” from correction targets.

As described above, according to one embodiment, the correction target determination module 483 may determine, as a correction target, a test target corresponding to category information which corresponds to a first level and does not correspond to a second level. The category corresponding to the first level may be a category of a test target belonging to a superordinate group according to the classification, and the category corresponding to the second level may be a category of a test target belonging to a subordinate group according to the classification.

In an embodiment, according to the comparison result acquired by the image comparison module 482, some metadata may be commonly associated with test targets belonging to the superordinate group and test targets belonging to the subordinate group. For example, although having the same ISO sensitivity, a first test target may belong to the superordinate group, while a second test target may belong to the subordinate group. In addition, specific recipe information (e.g. a scene category) may be commonly associated with a test target belonging to the superordinate group and a test target belonging to the subordinate group. As described above, images corresponding to the metadata or recipe information commonly associated with the superordinate group and the subordinate group may have less correction effect than expected. Accordingly, the correction target determination module 483 may exclude, from the correction targets, images having metadata or recipe information associated with the superordinate group and the subordinate group among the images stored in the databases (e.g. the raw image storage 479 or the image storage 480).

According to one embodiment, the correction target determination module 483 may determine a correction target on the basis of at least one of metadata or recipe information, as well as on the basis of the comparison result acquired by the operation of the image comparison module 482. For example, the correction target determination module 483 may identify metadata of test targets belonging to the superordinate group (hereinafter, referred to as an “upper metadata set”), and metadata of test targets belonging to the subordinate group (hereinafter referred to as a “lower metadata set”). The correction target determination module 483 may compare the upper metadata set and the lower metadata set to identify metadata (hereinafter, referred to as a “duplicate metadata set”) included in both the upper metadata set and the lower metadata set. The correction target determination module 483 may determine, as the correction targets, images that corresponds to one or more metadata of the upper metadata set and does not correspond to two or more metadata of the duplicate metadata set. For example, if the upper metadata set includes a first ISO sensitivity value, a second ISO sensitivity value, a first brightness value, a second brightness value, a first sharpness value, and a second sharpness value, and the first ISO sensitivity value, the first brightness value, and the first sharpness value are determined as duplicate metadata, images having the first ISO sensitivity value, the second brightness value, and the second sharpness value may be determined as correction targets. Images having the first ISO sensitivity value, the first brightness value, and the second sharpness value may be excluded from the correction targets.

According to an embodiment, the metadata may be received from an external device (e.g. the electronic device 400) together with an image, and may be stored in the database (e.g. the raw image storage 479 or the image storage 480) in association with the image. For example, the metadata may be information acquired by an image sensor (e.g. an image sensor 411), and may include a focal length, an auto focus area, information (orientation) related to left and right rotation during photographing, auto white balance (AWB), color space, exposure time, aperture-related information (e.g. F-number, F-stop), exposure program (e.g. auto, aperture priority, shutter priority, manual, etc.), ISO speed ratings (ISO), date of image capturing (data time original), etc. The metadata may also include information, such as illuminance at an image-capturing place or time stamp, sensed by a sensor or clock other than the image sensor.

According to an embodiment, the recipe information may include information (e.g. image segment, layer, vector, scene category, etc.) acquired by the image recognition module 473 by recognizing an image (e.g. small raw image) received from an external device (e.g. the electronic device 400).

According to an embodiment, the correction target determination module 483 may determine correction targets on the basis of a tuning policy (e.g. an effect). For example, when images are corrected by a correction method (e.g., the second ISP 476 b) to which modification (e.g. replacement or upgrade) has been applied, if the expected effect is an increase in brightness, the correction target determination module 483 may apply a weight to the difference value in brightness (e.g. may add a predetermined value to the difference value) so as to preferentially classify the test targets having brightness increased by the correction into the superordinate group.

The second electronic device 400 (e.g. the electronic device 101) according to an embodiment may include a camera module 410, a display 420, a first processor 430, a first memory 440, an input device 450, and a sound output device 460. The camera module 410 according to an embodiment may include an image sensor 411, a second processor 412, and a second memory 418. The second processor 412 according to an embodiment may include a raw image processing module 413, an ISP 416, and an encoder 417. At least some of operations performed by the second processor 412 may be performed by the first processor 430. The raw image processing module 413, the ISP 416, and the encoder 417 may be logical modules, and thus, operations performed thereby may be performed by the second processor 412 (e.g. the processor 120). In another embodiment, at least one of the raw image processing module 413, the ISP 416, and the encoder 417 may be implemented as separate hardware modules within the second processor 412.

Although not illustrated, the second electronic device 400 may include a communication module (e.g. the communication module 190 in FIG. 1) for data communication with the first electronic device 470, and the first electronic device 470 may also include a communication module for data communication with the second electronic device 400.

In an embodiment, the image sensor 411 (e.g. the image sensor 230 in FIG. 2 or the image sensor 321 in FIG. 3) may acquire various raw images of a subject. The image sensor 411 may acquire various types of raw images according to color filter array (CFA) pattern. The image sensor 411 may acquire a raw image having a dual pixel (DP) structure (or dual photodiode (2PD) structure) in which a pixel includes different parallax (or phase difference) information. The image sensor 411 may include multiple image sensors having identical or different characteristics (e.g. dual sensors (e.g. RGB+RGB, RGB+Mono, or Wide+Tele, etc.), or an array sensor (e.g. two or more sensors), etc.). The multiple image sensors may be used to acquire one or more raw images. The acquired raw images may be stored in the second memory 418 (e.g. DRAM) as is or after additional processing.

The raw image acquired according to an embodiment may be configured in various formats (e.g. Bayer format, etc.). The raw image may be represented by one of red (R), green (G), and blue (B) per pixel, and may be represented by a bit-depth of 8 to 16 bits. Various color filter array (CFA) patterns may be applied to the raw image. The raw image may have a layer structure including information on various colors (e.g. multiple colors of R, and B) for each pixel. According to various configurations of the image sensor, the raw image may include not only color information but also parallax (phase difference) information. Information (e.g. time, location, illuminance, etc.) related to capturing an image may be generated as metadata and stored in association with the raw image. For example, the second processor 412 may acquire metadata about the raw image using the image sensor 411. The metadata that can be acquired through the image sensor 411 includes, for example, focal length, auto focus area, information related to left and right rotation during image capturing (orientation), color space, and exposure time. In addition, the metadata may include location information of an image, which may be acquired through a sensor (e.g. a GPS sensor) different from the image sensor.

In an embodiment, the raw image processing module 413 may perform various processing on the raw image acquired from the image sensor 411. For example, the raw image processing module 413 may perform lens distortion correction or noise removal on the raw image.

The raw image processing module 413 according to an embodiment may include a small raw image generation module 414 and a compression module 415. The small raw image generation module 414 may generate a small raw image from a raw image by using various down-scaling methods (e.g. reducing the size or reducing the resolution) or down-sampling methods (e.g. taking only one or some of a series of sampled samples). The compression module 415 may compress the raw image or the small raw image by using various compression algorithms, and may store the compressed raw image or the compressed small raw image in the second memory 418. The small raw image may be temporarily or persistently stored in the second memory 418. The communication module (not shown) (e.g. the communication module 190) of the second electronic device 400 may transmit the small raw image stored in the second memory 418 to the first electronic device 470.

In an embodiment, the ISP 416 (e.g. the image signal processor 260 in FIG. 2 or the ISP 323 in FIG. 3) may perform image processing on a raw image stored in second memory 418. For example, the ISP 416 may process (e.g. correct) the raw image by using recipe information (e.g. image segment, layer, vector, scene category, etc.) acquired from the first electronic device 470 through the communication module in various ways. According to one embodiment, the ISP 416 may transmit the raw image or the small raw image to the first electronic device 470 through the communication module so that the first electronic device 470 generates recipe information for image processing. The ISP 416 may process the raw image by using the recipe information acquired from the first electronic device 470 through the communication module. The ISP 416 may compress the processed raw image into, for example, JPEG and may store the same in the first memory 440.

In an embodiment, the ISP 416 that performs image processing in the second electronic device 400 may be changed from a first ISP 416 a to a second ISP 416 b. For example, the second ISP 416 b may have a correction method in which at least a part of the correction method of the first ISP 416 a has been upgraded.

In an embodiment, the encoder 417 may encode the raw image processed by the ISP 416 to generate an image file (e.g. JPEG, MPEG, 360 degree panorama, etc.), and may store the image file in the first memory 440.

In an embodiment, the first processor 430 (e.g. the processor 120 in FIG. 1) may be electrically connected to the camera module 410, the display 420, the first memory 440, the input device 450, the sound output device 460, and the communication module (not shown) so as to control at least one thereof. Further, the first processor 430 may perform various data processing and operations.

According to an embodiment, the first processor 430 may update an image stored in the first memory 440 in response to the fact that the ISP 416 has changed from the first ISP 416 a to the second ISP 416 b. For example, the first processor 430 may perform functions identical to at least some functions of the processor 471 of the first electronic device 470 (e.g. at least one among the test target acquisition module 481, the image comparison module 482, and the correction target determination module 483).

According to an embodiment, an electronic device (e.g. the electronic device 101 in FIG. 1 or the second electronic device 400 in FIG. 4) may include: a camera (e.g. the camera module 180 in FIG. 1) including an image sensor (e.g. the camera module 180 in FIG. 1, the image sensor 230 in FIG. 2, the image sensor 321 in FIG. 3, or the image sensor 411 in FIG. 4); a communication module (e.g. the communication module 190 in FIG. 1); a memory (e.g. the memory 130 in FIG. 1, the memory 250 in FIG. 2, or the memory 325 in FIG. 3); and a processor (e.g. the processor 120 in FIG. 1, the image signal processor 260 in FIG. 2, the ISP 323 in FIG. 3, or the first processor 430 or the second processor 412 in FIG. 4) operationally connected to the camera, the communication module, and the memory. The memory may store instructions that, when executed, cause the processor to: acquire a first image including an external object by using the camera; acquire a second image including less information than the first image by using at least a part of the first image; transmit the second image to an external electronic device (e.g. the electronic device 104 or the server 108 in FIG. 1, the external electronic device 300 in FIG. 3, or the first electronic device 470 in FIG. 4) by using the communication module; receive security information corresponding to the second image from the external electronic device by using the communication module; and secure the first image, at least partially based on the security information.

According to an embodiment, the security information corresponding to the second image may relate to at least one biometric information segment of the external object.

FIG. 5 is a flowchart illustrating a method for securing personal information included in an image in an electronic device according to an embodiment.

Referring to FIG. 5, in operation 510, according to an embodiment, the processor 120 of the electronic device 101 (e.g. the second electronic device 400 in FIG. 4) may acquire a first image including an external object by using a camera including an image sensor (e.g. the camera module 180 in FIG. 1, the image sensor 230 in FIG. 2, the image sensor 321 in FIG. 3, or the image sensor 411 in FIG. 4). The first image may be a raw image (e.g. the raw image 322 in FIG. 3) and/or an image (e.g. a JPEG image) obtained by processing or correcting the raw image.

According to an embodiment, the first image may be in various formats (e.g. Bayer format, etc.). The first image may be represented by one of red (R), green (G), and blue (B) per pixel, and may be represented by a bit-depth of 8 to 16 bits. Various color filter array (CFA) patterns may be applied to the first image. The first image may have a layer structure including information on various colors (e.g. multiple colors of R, G, and B) for each pixel. According to various configurations of the image sensor, the first image may include not only color information (e.g. RGB) but also phase difference information. Information (e.g. time, location, illuminance, etc.) related to capturing of the image may be generated as metadata and stored in association with the first image.

In operation 520, according to an embodiment, the processor 120 of the electronic device 101 may acquire a second image including less information than the first image by using at least a part of the first image. The second image may be a small image (the small raw image 326 in FIG. 3) related to the raw image and/or a small image of a processed image (e.g. a JPEG image).

According to an embodiment, the processor 120 may generate the second image by reducing the data in the first image. For example, the processor 120 may generate the second image from the first image by using various down-scaling methods or down-sampling methods. The data volume of the second image may be smaller than that of the first image due to the processor 120 adjusting the resolution of the first image, filtering the first image through one or more frequency bands, and/or selecting one or more bit-plane levels of the fir image. The processor 120 may generate the second image by extracting a low-frequency band from the first image. The processor 120 may generate the second image by selecting some from among the multiple bit-plane levels of the first image.

In operation 530, according to an embodiment, the processor 120 of the electronic device 101 may transmit the second image to the external electronic device 300 (e.g. the electronic device 104 or the server 108 in FIG. 1 or the first electronic device 470 in FIG. 4) through the communication module (e.g. the communication module 190 in FIG. 1).

According to an embodiment, the processor 120 may transmit the second image having a smaller capacity than the first image to the external electronic device 300 such that the external electronic device 300 generates security recipe information for securing the first or second image. According to one embodiment, the processor 120 may request security recipe information from the external electronic device 300 so as to divide the second image into a first security level segment and a second security level segment requiring higher security than the first security level segment.

According to an embodiment, the security recipe information may be used to divide the second image into multiple security level segments (e.g. three security level segments). In this instance, multiple servers may process the second image for multiple security levels. For example, a first server may be configured to process a first security level segment included in the second image, and a second server may be configured to process a second security level segment. In another example, a third security level segment may be processed by the electronic device 101.

In operation 540, according to an embodiment, the processor 120 of the electronic device 101 may receive security information included in the second image from the external electronic device 300 by using the communication module (e.g. the communication module 190 in FIG. 1).

According to an embodiment, the external electronic device 300 may use the second image to recognize at least one image segment. For example, the external electronic device 300 may determine at least one image segment (e.g. a security segment) that includes personal information.

According to an embodiment, instead or in addition to determining personal information (e.g. fingerprint information, iris information, or face information), the external electronic device 300 may apply an object recognition algorithm or a text recognition algorithm to the second image so as to identify an object (e.g. a person) or recognize a specific segment of the object (e.g. “the person's face,” “the person's eye,” or “the person's hand”). For example, the external electronic device 300 may identify an object (e.g. a driver's license) in the second image, but may not determine personal information (e.g. license number) included in the object.

According to an embodiment, the external electronic device 300 may include at least one image segment (e.g. “the person's face,” “the person's eye,” or “the person's hand”) of the second image, which is considered to include personal information, in security information, and may transmit the same to the electronic device 101. According to one embodiment, the security information may include location information (e.g. pixel coordinates) of at least one image segment considered to include personal information and/or identification information (e.g. “the person's face,” “the person's eye,” or “the person's hand”) of each of image segments.

According to an embodiment, the external electronic device 300 may transmit correction segment information (e.g. the correction segment information 332) to the electronic device 101 together with the security information of the second image.

In operation 550, according to an embodiment, the processor 120 of the electronic device 101 may secure the first image, at least partially based on the security information.

According to an embodiment, the processor 120 may divide, at least partially based on the security information, the first image into a first security level segment and a second security level segment.

According to an embodiment, the processor 120 may generate a security key as a part of the method for securing the first image and store the security key in the memory, may acquire a third image in which the second security level segment of the first image has been encoded based on the security key, and may transmit the third image to the external electronic device 300. For example, the processor 120 may acquire the third image by mosaicking, masking, or scrambling the second security level segment of the first image. According to an embodiment, the processor 120 may receive, from the external electronic device 300, a fourth image in which the first security level segment of the third image has been at least partially corrected, and may acquire a fifth image in which the fourth image has been decoded using the security key stored in the memory 130.

According to an embodiment, as a part of the method for securing the first image, the processor 120 may extract the first security level segment from the first image and generate the third image including the first security level segment, and may extract the second security level segment from the first image and generate a security segment image including the second security level segment. According to an embodiment, the processor 120 may transmit the third image to the external electronic device 300 and may store the security segment image in the memory 130.

According to an embodiment, the processor 120 may receive, from the external electronic device 300, the fourth image in which the third image has been at least partially corrected, and acquire the fifth image by using the fourth image and the security segment image.

FIG. 6 is a flowchart illustrating a method for securing a first image in an electronic device according to an embodiment. The operations in FIG. 6 may be included as a part of operation 550 or the entirety thereof in FIG. 5.

Referring to FIG. 6, in operation 610, according to an embodiment, the processor 120 of the electronic device 101 may acquire a third image in which a second security level segment of the first image has been encoded based on the security key.

According to an embodiment, security information included in a second image received from the external electronic device 300 (e.g. the electronic device 104 or the server 108 in FIG. 1 or the first electronic device 470 in FIG. 4) may include security recipe information used to divide the second image into a first security level segment and/or a second security level segment requiring higher security than the first security level segment. The processor 120 may divide, at least partially based on the security information or the security recipe information, the first image into a first security level segment and a second security level segment. According to an embodiment, the first image may be divided into multiple security segments (e.g. three security level segments) according to the security information or the security recipe information.

According to an embodiment, the processor 120 may provide, based on the security information received from the external electronic device 300, a user with an image indicating at least one security segment, and may determine the first security level segment and the second security level segment on the basis of a user input selecting a part of the at least one security segment or the entirety thereof. For example, the processor may display at least one security segment (e.g. “a person's face,” “a person's eye,” or “a person's hand) in the provided image, and, if the user selects a specific segment (e.g. “the person's eye”), may designate the selected specific segment (e.g. “the person's eye”) as the second security level segment.

According to an embodiment, the processor 120 may receive a user input designating another segment (e.g. a segment of the image showing a document) other than the at least one security segment within the provided image, and may determine the designated another segment as the second security level segment.

According to an embodiment, the processor 120 may generate a security key and then may store the security key in the memory. The processor 120 may generate the encoded third image from the first image by using the security key and a hash function.

In operation 620, according to an embodiment, the processor 120 of the electronic device 101 may transmit the third image to the external electronic device 300 (e.g. the electronic device 104 or the server 108 in FIG. 1, or the first electronic device 470 in FIG. 4) through the communication module (e.g. the communication module 190 in FIG. 1). For example, the third image may have the second security level segment which has been mosaicked, masked, and scrambled.

In operation 630, according to an embodiment, the processor 120 of the electronic device 101 may receive a fourth image, in which the first security level segment of the third image is corrected, from the external electronic device 300 through the communication module (e.g. the communication module 190 in FIG. 1).

According to an embodiment, the external electronic device 300 may correct at least a part of the first security level segment. For example, the external electronic device 300 may correct the first security level segment by using the existing generated correction segment information (e.g. the correction segment information 332), or may correct the first security level segment by using extended correction segment information. The external electronic device 300 has no security key used for the third image, and thus may not determine the second security level segment. For example, the external electronic device 300 may not correct the second security level segment.

In operation 640, according to an embodiment, the processor 120 of the electronic device 101 may decode the fourth image on the basis of the security key stored in the memory 130 and then acquire the fifth image.

According to an embodiment, the processor 120 may acquire the fifth image only by decoding the fourth image. For example, the processor 120 may demosaic, unmask, or unscramble the second security level segment in the fourth image. According to an embodiment, the processor 120 may decode the fourth image and then correct the second security level segment using the correction segment information (e.g. the correction segment information 332), thereby acquiring the fifth image. The fifth image may be stored in the memory 130.

It is to be understood that if an element (e.g., a first element) is referred to, with or without the term “operatively” or “communicatively”, as “coupled with,” “coupled to,” “connected with,” or “connected to” another element (e.g., a second element), it means that the element may be coupled with the other element directly (e.g., wiredly), wirelessly, or via a third element.

As used herein, the term “module” may include a unit implemented in hardware, software, or firmware, and may interchangeably be used with other terms, for example, “logic,” “logic block,” “part,” or “circuitry”. A module may be a single integral component, or a minimum unit or part thereof, adapted to perform one or more functions. For example, according to an embodiment, the module may be implemented in a form of an application-specific integrated circuit (ASIC).

Various embodiments as set forth herein may be implemented as software (e.g., the program 140) including one or more instructions that are stored in a storage medium (e.g., internal memory 136 or external memory 138) that is readable by a machine (e.g., the electronic device 101). For example, a processor (e.g., the processor 120) of the machine (e.g., the electronic device 101) may invoke at least one of the one or more instructions stored in the storage medium, and execute it, with or without using one or more other components under the control of the processor. This allows the machine to be operated to perform at least one function according to the at least one instruction invoked. The one or more instructions may include a code generated by a compiler or a code executable by an interpreter. The machine-readable storage medium may be provided in the form of a non-transitory storage medium. Wherein, the term “non-transitory” simply means that the storage medium is a tangible device, and does not include a signal (e.g., an electromagnetic wave), but this term does not differentiate between where data is semi-permanently stored in the storage medium and where the data is temporarily stored in the storage medium.
